How does the EHIC card affect travel insurance in the Canary Islands?
The Canary Islands are a part of Spain and so are in the EU – so it's a good idea to take a European Health Insurance Card (EHIC) with you. This isn't a substitute for travel insurance, but it gives you the right to state medical treatment on the same terms as other EU nationals.
One of the advantages of carrying and using an EHIC is that some insurance providers may waive your excess in the event of a medical claim. The cards are free, so simply apply for one from the NHS website – and don't get caught out by websites that charge you.
